What the...? Nikkei Futures Plunge

From ZeroHedge:

Just your ordinary, stomach-churning, price stability-confirming, 600 point intraday swing in the Nikkei June Future contract, which after taking out the 13,000 support plunged by a ridiculous 200 points in milliseconds. Mrs Watanabe will not be happy when she wakes up. It may be time for the BOJ to raise its hilarious assessment of Japanses GDP once again just to completely lose all credibility. Goldman is thiiiis close to being closed out on its buy Nikkei225 September futs reco from Sunday night (stop of 12,750). On a serious note, keep an eye out for BOJ intervention - the time is fast approaching.
